MysteryStat

A server operator uses commands to add a mystery statistic objective, activate it, and show its scores in the player list display slot. Several challenges can be defined and set up independently, and they can run at the same time, but only one of them occupies the player list at once. Commands can also start and restart the server-side challenge flow, so a game can be reset without rebuilding the objective list by hand.

Scores for a challenge can be read by anyone with the proper permission: the top three players for the active objective, or the top three for any objective that was provided. A challenge can be removed, and an existing vanilla objective can be copied into a mystery challenge so its scores carry over. Permissions cover adding, activating, listing, clearing and publishing, which lets an operator decide who may run each action.

The mod depends on Fabric API, which must be installed alongside it on the server. Because the environment is server-side only, players join without installing anything. MysteryStat is published for Fabric across four game versions, 1.20.4 – 1.21, and is released under the MIT License as open source.
